The grren_led should only go OFF when the same button_status is pressed again. 2. button_fall, when this button is pressed, the audio alarm from the buzzer is heard. This audio alarm should be silenced by button_safe only. 3. button_safe, when pressed, yellow_led should go ON, and at the same time the buzzer be silenced. The yellow_led should stay ON until the button_status is pressed to swich off the device. 4. potentimeter, a threshold is set, whenever the potentiometer value goes above the set threshhold, the red_led go ON. When potentiometer value is below the set threshold, the red_led go OFF. I need help in improving my code because it does not meet all the requirements above.
